CAN SURFACE RAMAN-SPECTROSCOPY BE A GENERAL TECHNIQUE FOR SURFACE SCIENCE AND ELECTROCHEMISTRY

Surface-enhanced Raman spectroscopy has almost been restricted to the study of only three noble metals of Au, Ag and Cu for two decades. Rec ently, a new confocal Raman microscope and special surface pretreatmen ts have allowed the acquisition of high-quality surface Raman spectra of organic and inorganic molecules adsorbed on bare Pt, Ni, Co, Fe, Pd , Rh, Ru and Si electrodes over a wide applied potential range for the first time. The present results demonstrate several advantages of in situ surface Raman spectroscopy that could probably make it a general technique widely used in surface science and electrochemistry.
